1. 6. Sensors for intelligent and reliable components

   Magister-uppsats, KTH/Skolan för industriell teknik och management (ITM)

   Författare :Pontus Lundman; [2020]
   Nyckelord :Wind turbine; Gearbox; Sensor; Condition monitoring; Cyber-physical system; Vindkraftverk; Växellåda; Sensor; Tillståndsövervakning; Cyberfysiskt system;

   Sammanfattning : One way to tackle the climate change society is facing today is through the change to renewable energy sources, such as wind power. Today, a trend when it comes to technology is that products are evolving into becoming more cyber-physical systems (CPS) by integrating functions realized with mechanics, control and communication.

3. 7. Detection of Long Term Vibration Deviations in GasTurbine Monitoring Data

   Master-uppsats, Linköpings universitet/Fordonssystem

   Författare :Johan Hansson; [2020]
   Nyckelord :Machine Learning; Vibrations;

   Sammanfattning : Condition based monitoring is today essential for any machine manufacturer tobe able to detect and predict faults in their machine fleet. This reduces the maintenancecost and also reduces machine downtime. LÄS MER

4. 8. Fault detection of planetary gearboxes in BLDC-motors using vibration and acoustic noise analysis

   Master-uppsats, Uppsala universitet/Institutionen för elektroteknik

   Författare :Henrik Ahnesjö; [2020]
   Nyckelord :Planetary gearbox; Fault detection; Condition Monitoring; Support Vector Machine SVM ; Machine Learning; Supervised Machine Learning; Defect Pinion; Defect Planet Gear; MATLAB; LabVIEW; Soundproof-box; Noise Vibration Harshness NVH ; Gearmesh Frequency GMF ; Power Spectrum; BLDC-motor;

   Sammanfattning : This thesis aims to use vibration and acoustic noise analysis to help a production line of a certain motor type to ensure good quality. Noise from the gearbox is sometimes present and the way it is detected is with a human listening to it. This type of error detection is subjective, and it is possible for human error to be present.

5. 9. Vibration analysis for predictive maintenance of a rotary pump. : Optimal accelerometer configuration based on vibration analysis for cavitation detection of a bi-winged positive displacement pump.

   Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

   Författare :Gustav Osswald; [2019]
   Nyckelord :;

   Sammanfattning : Predictive maintenance based on condition monitoring uses sensor and system data to prevent damage, in advance to a failure occurring, allowing for a service to be performed at an optimal position in time. Condition based predictive maintenance estimates time of system failure based on a priori information, which has shown to be much more cost effective than traditional maintenance methods. LÄS MER

7. 10. Vibration analysis for condition monitoring of mechanical presses

   Master-uppsats, Lunds universitet/Industriell Produktion

   Författare :Julia Runesson; [2019]
   Nyckelord :Vibration analysis; Predictive maintenance; Condition monitoring; Mechanical press; Press maintenance; PSD; DFT FFT; RMS; Kurtosis; Technology and Engineering;

   Sammanfattning : In a world where the concept of just-in-time has been lifted outside of the manu-facturing world and onto the market, the increasing demand of luxury wares like cars is accompanied only by tougher industrial conditions and no room for error. Loss of productivity and decrease in efficiency can be devastating to any manufac-turing company in today’s market climate. LÄS MER
